Allen-Bradley servo motor repair

Star Automations repairs Allen-Bradley servo motors, including MP-Series, TL-Series and older Y and H series motors used with Kinetix and Ultra drives. The motor is inspected, the failed parts are repaired or replaced, the encoder is aligned where needed, and the motor is proved on our servo motor test system with a no-load run and a full-load test before it leaves our Chennai bench. We are not a Allen-Bradley dealer or service partner; the brand name describes the motor we repair.

01Families

Allen-Bradley motor families we inspect, repair and test

The catalogue number on the nameplate decides what can be done. MPL is the Kinetix MPL low-inertia series, MPM the Kinetix MPM medium-inertia series and VPL the Kinetix VP low-inertia series.

We repair Allen-Bradley MPL, MPM, VPL, TL-series and older 1326AB servo motors. Each motor is inspected, repaired, its feedback tested and aligned, and then given a final run test on our universal servo motor test system before it is returned with a test report.

For the MPL-B series in detail, see Allen-Bradley MPL-B servo motor repair and service, and how to read an Allen-Bradley servo part number.

  • MPL low-inertia motors
  • MPM medium-inertia motors
  • VPL low-inertia motors
  • TL-series motors
  • 1326AB motors
  • Feedback: resolvers, Hiperface and other absolute encoders, tested and aligned

Final run test after repair

An Allen-Bradley Kinetix MPL servo motor after repair, running on an Allen-Bradley Ultra3000 drive: drive enabled, speed and current feedback checked before the motor is released.

Every repaired motor gets a run test and a printed test report. See the real tester screens and run test.

01Failures

Common Allen-Bradley servo motor failures

Feedback faults

Hiperface and resolver feedback alarms from encoder failure or cable damage.

Bearing and seal wear

Noise and contamination on motors in washdown and packaging lines.

Winding insulation

Ground faults from moisture in the winding.

Brake faults

Holding brakes that slip or do not release.

02Test bench

What the test bench checks

Allen-Bradley motors are tested on our servo motor test system without a Kinetix drive, then loaded on the rig.

  • Insulation resistance and hi-pot
  • Winding resistance and balance
  • Encoder or resolver feedback and commutation offset
  • Brake release and holding, where fitted
  • No-load run, then full-load run; speed and current against the nameplate
  • Vibration and noise at rated speed
03Repair or replace

Repair or replace

Repair suits MP-Series and older frames where the encoder, bearings, seal or brake failed and the frame is sound, and where a new motor would mean a long wait.

Replacement suits motors with mechanical damage or repeated winding failures. We give you the findings and photos so the decision is yours.

05How to send

How to send the motor

You can send a servo motor from anywhere in India. Talk to us before you courier, so the unit is expected and logged on arrival.

  1. Send the nameplate

    WhatsApp a clear photo of the nameplate, the alarm code and what the machine was doing when it failed.

  2. We confirm repairability

    We tell you whether we can test and repair that model before anything is shipped.

  3. Courier or pickup

    Courier the motor to our Chennai bench, or ask us to arrange pickup where needed.

  4. Inspection and quote

    The motor is opened, inspected and photographed. You get the findings and a quote before work starts.

  5. Repair, test, dispatch

    Repaired, run-tested and load-tested, then dispatched with a printed test report.

06Questions

Allen-Bradley servo motor questions

More on the FAQ page.

Do you repair Allen-Bradley servo motors?

Yes, including MP-Series, TL-Series and older Y and H series motors used with Kinetix and Ultra drives. Send the nameplate and we confirm before you courier.

Do you repair motors from washdown lines?

Yes. Water ingress damage to encoders, bearings and seals is a common repair. We replace seals and note the cause on the report.

What should I send for a quote on a Allen-Bradley motor?

A photo of the nameplate, the alarm code and a note on the symptom. We confirm repairability before you courier.

Do you need a Allen-Bradley drive to test the motor?

No. Our servo motor test system runs Allen-Bradley motors without the original drive, then a load rig applies full load.

Is there a warranty?

A written warranty is given after a successful repair. Warranty terms are stated on each quotation.
